Well, I consulted my handy Mineralogical Society Planetary Materials volume
36 and it makes no mention of vesiculs in aubrites. I'll be interested to
see what Bernd finds :)
What part of the stone did you find the vesicles in? Near the edge or
center? In any particular phase or phases? If so, which ones? Are they
randomly distributed/form any type of pattern? What do the contacts with
the minerals look like?
Keep us posted on what you find out.
